Pressure myography on an open source, 3D-printed microscope using Raspbery PI

 

The Pachter lab has shared their designs for the Poseidon project created at the California Institute of Technology. Poseidon is a 3D-printed  syringe pump and microscope system designed for microfluidic experiments, and it is described in a preprint published on bioRxiv. The complete system is controlled by a tiny Raspberry Pi computer and comes with a 7" touchscreen interface!We've been adapting the Poseidon microscope design for use with our pressure myographs. We've even rewritten our diameter tracking software to run with on the Raspberry Pi.

Pressure myographs require some way to image the blood vessel mounted in the chamber. We’ve been recommending cheap upright AmScope microscopes that you can get on Amazon, or Nikon’s cheapest inverted offerings. But we thought it would be nice if VasoTracker had its own open source microscope. So we’ve been adapting the Poseidon microscope design for use with our pressure myographs. We’ve even rewritten our diameter tracking software to run on the Raspberry Pi.

All in, the microscope costs less than £150 to make! Check back here soon for an update!
